Security audit

Jtexpress

Security checks for vulnerabilities and agentic risk

Overview

This J&T Express helper is coherent and disclosed, with limited local storage only for shipment-related workflows if local runtime features are used.

Before installing, be aware that using local runtime features may store shipment history, subscriptions, and possibly address records under ~/.openclaw/data/jtexpress/. Use the documented privacy info, export, and clear commands if you want to inspect or remove that local data.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (2)

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

## Local Persistence

When the local CLI/runtime code is used, this skill may create and persist local data under:

- `~/.openclaw/data/jtexpress/jtexpress.db`
  - stores query history

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The README is entirely written in Chinese and all example interactions assume Chinese-language use, with no indication that users may choose another language or that the skill is intentionally restricted to a Chinese-speaking or region-specific audience. Under the policy rule, forcing a specific language without user opt-in is a natural-language policy concern.
